The nervous system is like the body’s communication network. It lets animals sense their environment, process information, and respond quickly. Basically, it helps the animal survive by controlling everything from movement to reflexes.

Key Points You Need to Know

• Purpose: Coordinates body activities and responses to the environment.
• How it works: Receives signals from the environment - processes them - sends instructions to muscles or glands.
• Importance: Without a nervous system, an animal can’t sense danger, find food, or move properly.
